Co-Ni/Al2O3 Catalysts for CO2 Methanation at Atmospheric Pressure

K. Nifantiev, O. Byeda, B. Mischanchuk, E. Ischenko


The methanation of carbon dioxide under atmospheric pressure on a Co-Ni/Al2O3 catalyst containing 5 wt% of metals prepared by the impregnation method was studied. Temperature of 95% conversion CO2 for all catalysts been studied falls into range 320-450°C at conditions of SV 100ml/min, 0.1 MPa pressure, and composition of feeding gas mixture CO2 – 2%, H2 – 55%, He – 43%. Methane selectivity was sufficiently high – up to 98%.
